1 VME Dual Sonar Board, P/N: 201850-xxx

The Prizm VME Dual Sonar Board provides two independent fiber optic links to remote the

Reson 8xxx and Simrad EM3002 single/dual beam sonars. The Dual Sonar Board can be

jumper selected to support both single-ended (single coax) Reson sonars and differential

(dual coax) Simrad sonars. This board only provides for the sonar’s uplink (subsea to

surface) data link, the downlink (surface to subsea) control link must be handled through

another separate multiplexer. The control link for the Reson and Simrad sonars may require

specific electrical protocols (i.e. RS-232, RS-485, RS-422 or other) and the sonar

manufacturer’s interface manual should be consulted.

The Dual Sonar Board can be jumper configured to operate as either a subsea or surface

interface board, so can be used as spare for either location. The optical modules used on the

board (pluggable small-form-factor (SFP)) are inherently bi-directional and care must be

taken to ensure the correct optical port (either TX or RX) is connected, depending on the

board configuration and system location. While the optical module’s receiver will operate

on all of the 16 CWDM wavelengths (1270 to 1610nm), the module’s transmitter only emits

at a single wavelength so care must be taken to ensure the correct wavelength is used.

The Dual Sonar Board supports PMON II diagnostics through the RS-485 diagnostics cable.

Diagnostics will display the optical parameters from both of the SFP modules and will also

show the sonar activity (both into and out of the board) on PMON II. Note: to acquire

diagnostics from the remote Dual Sonar Board, the board must be connected to an RS-485

channel on a Submux RS-485 daughterboard.

1.1 VME Dual Sonar Board Revision History:

The VME Dual Sonar Board has gone through the following printed circuit board (PCB)

and Assembly revisions:

PCB Revision A/Assembly Revision A Original design.

1.2 VME Dual Sonar Board Dash (-) Number Definitions

The VME Dual Sonar Board has a Dash Number appended to the part number. This

Dash Number identifies the specific board configurations:

-001x 50-Ohm SMB connectors

NOTE: the x after the dash number denotes the assembly revision letter.

1.3 VME Dual Sonar Board Operation:

Each independent sonar link has two 50-ohm SMB coaxial connectors. These connectors

will be active as inputs or outputs depending on the jumper settings. For single-ended

(single coax) sonars, only the top SMB connector will be active (labeled IN/OUT A+ or

IN/OUT B+). For differential (dual coax) sonars, both of the connectors will be used.


Page 4 of 14

NOTE: While 50-Ohm SMB connectors are standard, Prizm supports both the 50-

Ohm and the 75-Ohm SMB connectors to meet the customer’s needs.

The sonar fiber links are identified as link “A/#1” or “B/#2”.

Normally, DC operating power for the board is supplied via the DIN backplane connector.

Alternately, there is single green 2-pin Phoenix connector on the on the right side of the

board for supplying the board with +5VDC. Pin 1 is the +5VDC input and pin 2 is the

ground. There is single black 3-pin Phoenix connector on the on the bottom left side of the board for

RS-485 diagnostics. Pin 1 is the RT+ signal, pin 2 is the ground/shield and pin 3 is the RT-

signal. A Prizm Diagnostics cable can be connected directly to this 3-pin connector or

through a RS-485 channel on a Submux RS-485 daughterboard.

NOTE: To complete the RS-485 diagnostics link from the surface to the subsea boards, the Dual Sonar

Board must be stacked onto a VME Video RS-485 channel on a Submux RS-485 daughterboard to

complete the link over the multiplexer’s fiber. Dual Sonar Board Indicators and Controls:

sonar configurations known to date: Subsea Reson 8125, Surface Reson 8125, Subsea

Simrad EM3002, and Surface Simrad EM3002.

Figures to be inserted here.

1.3.2 VME Dual Sonar Board Specifications:

Number of Sonar links: 2 per board

Sonar type supported: Reson 8xxx or Simrad EM3002

Data rates supported: Depends on sonar

Maximum Sonar data rate: 600Mbps

1.3.3 VME Dual Sonar Board Dimensions:

Printed circuit board (PCB): 3.937 in x 6.299 in x 0.80 in board-to-board

(100mm x 160mm x 15.24 mm)

1.3.4 Dual Sonar Board Power Requirements:

The Dual Sonar Board utilizes approximately 650mA @ 5VDC.

1.3.5 Power Section Testing


Page 12 of 14

NOTE: The connectors on the bottom of the Dual Sonar Board have pins that are

connected to +5VDC and ground. If these pins are inadvertently shorted together or to a

common chassis ground, the board fuse (F1) will trip/reset.

If both the +5V Power LED +3.3V Power LED are out:

• Check for continuity of PTC fuse F1 with an ohmmeter.

• Replace PTC fuse if open.

If only the +5V Power LED is out:

• Verify +5V DC is present at the source

• At J9 if powered off of external power

• At J8 if powered off of the backplane

• If +5V is not available replace the board with a spare.

• If +5V is available check the display LED (D21).

If only the +3.3V Power LED is out:

• Verify +5VDC at F1 (replace board if +5VDC is not available)

• Verify +3.3VDC across C127 on top of board

• If +3.3V is not available replace the board with a spare.

• If +3.3V is available check the display LED (D22).

1.3.6 Optical Section Testing

For surface boards, if the “FIBER 1” or “FIBER 2” LED is off or flickering, one or more

of the following conditions is likely:

• The fiber is broken or damaged.

• The optical transceiver module is defective at either the surface or subsea board.

• Excessive light loss (low received optical power) is being experienced.

• The VME board (not the optical transceiver module) is malfunctioning.

• There is not enough attenuation in the optical link and the receiver is saturating.

If excessive optical loss is being experienced, the following conditions may be present:

• May have sonar data errors.

• Check the optical level with an optical power meter and inspect all fiber optic

connections including CWDMs and slip rings.

To determine if the fiber is broken, a laser module is out, or the board is malfunctioning,

first:

• Verify that the optical transceiver is tight in its socket.

• Verify that shunts (jumpers) are placed per system jumper configuration.

• Check all fiber optic connections including CWDMs and slip rings to make sure that

they are not causing the problem.

• Check that the optical fiber cable is straight at connectors on board for minimum

optic loss.

1.4 VME System Installation Checkout Procedure

NOTE: The Dual Sonar Board will work in a stand-alone configuration without an RS-

485 channel on a Submux RS-485 daughterboard. Without an RS-485 channel on a

Submux RS-485 daughterboard, the subsea diagnostics will not work but the board will

still carry a sonar signal.

For this VME System installation checkout procedure, it is assumed that the VME System is

composed of a Sonar board mounted in the vehicle and a Sonar board on the surface.

+5VDC power for the VME boards is supplied by the user’s DC power supply powering the

VME rack and should be verified to be between +4.75VDC and +5.25VDC at the 2-pin

Phoenix power connector or at the backplane.

1.4.1 Diagnostics Overview

The Dual Sonar Board has been designed to include hardware and firmware for monitoring

various parameters of interest. This capability is accessed via a 3-pin Phoenix connector on

the board that carries bi-directional RS-485 telemetry. The diagnostics will typically be

used in conjunction with a user-supplied PC on the surface, which has been loaded with

PRIZM Modem Monitoring S/W (PMON II).

For the Dual Sonar board, the Diagnostics feature requires that there be a functioning

multiplexer system for connectivity between the topside Diagnostic PC and the remote

multiplexer.

NOTE: The diagnostics feature in no way interferes with normal operation of the

modem – it is not necessary to be running the diagnostics software for any of the

VME boards to work.

1.4.2 Required Communications Hardware for Diagnostics

The diagnostics capability is accessed via the 3-pin Phoenix connector on the VME boards,

which provides the RS-485 connectivity to the on-board processor for diagnostics

communications. RS-485 was used because of its multi-drop capability, which in this case

allows all the VME boards to be communicated with via a single channel. In this

configuration, no RS-485 multiplexer channel is needed.

The user is required to communicate with the VME boards of the system via RS-485. A

typical installation is shown in the following drawing. This details a diagnostic connection

from a Windows PC running PMON II to a VME system.
